When the nut is vibrated after connection, it is very easy for the nut to rotate, causing the bellows connection to become loose and unstable, resulting in leakage, which in turn causes the bellows connection to become loose and unstable. Utility Model Content

A blocking ring is slidably connected to the inner wall of the sliding groove on the surface of the fixing part, and three push blocks are fixedly connected to the surface of the blocking ring, and the push blocks are slidably connected to the inner walls of the rectangular holes. Through the above components, the push blocks drive the blocking ring to move, and the blocking ring can block the screw part to improve the appearance. At the same time, the blocking ring fits with one end of the screw to prevent the screw from rotating.

[0010] Preferably, a groove is provided on the surface of the auxiliary rod, and a limiting rod is fixedly connected to the inner wall of the sliding groove on the surface of the nut body. The limiting rod is engaged with the inner wall of the groove. Through the above components, when the limiting rod is inserted into the limiting groove on the surface of the auxiliary rod, the auxiliary rod can be kept in a horizontal state.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, when the equipment is connected with the interface, the nut body on the pipe body is rotated, and the nut body cooperates with the threaded end of the interface to achieve connection. By setting a stabilizing device, when the pipe body is connected through the nut body, the screw is turned, and the screw can drive the auxiliary ring to be inserted into the corresponding slot on the surface of the connecting piece.

By setting a stabilizing device, the stability effect of the bellows after connection can be improved, and the existing bellows can be effectively reduced. When the connection is carried out, the main threaded connection method is adopted. When the nut is vibrated after connection, the nut is very likely to rotate, which leads to the loosening and instability of the bellows connection and leakage, thereby improving the stability effect of the bellows after connection.

[0020] See also Figure 1-5 The utility model provides a technical solution: a connected and fastened corrugated pipe, comprising a pipe body 1 and a stabilizing device 4, two connecting pieces 2 are installed on the surface of the pipe body 1, a nut body 3 is rotatably connected to the surface of the connecting piece 2, and the stabilizing device 4 is arranged on the surface of the nut body 3.

[0021] The specific configuration and functions of the stabilizing device 4 and the auxiliary device 5 will be described in detail below.

[0022] Specifically, the stabilizing device 4 includes a fixing part 41, and there are two fixing parts 41. The two fixing parts 41 are fixedly connected to the surfaces of the two nut bodies 3 respectively. The surface of the fixing part 41 is provided with three groups of mounting holes. The inner walls of the three groups of mounting holes are threadedly connected with screws 44. One end of the screw 44 is fixedly connected with an auxiliary ring 45. The surface of the connecting part 2 is provided with three groups of slots 48. The screws 44 and the auxiliary rings 45 are both plugged into the inner walls of the slots 48.

[0023] In this embodiment: after the tube body 1 is connected to the device interface by rotating the nut body 3, the screw 44 is rotated, and the screw 44 drives the auxiliary ring 45 to be inserted into the slot 48 on the surface of the connector 2, thereby limiting the rotation of the nut body 3 and reducing the self-rotation caused by vibration, which leads to unstable connection and easy leakage affecting normal use.

[0024] Specifically, a limiting groove 47 is provided on the inner wall of the fixing member 41 near the slot 48 on the surface of the connecting member 2, and the auxiliary ring 45 is plugged into the inner wall of the limiting groove 47. When the screw 44 drives the auxiliary ring 45 to be pulled out from the slot 48, the screw 44 will drive the auxiliary ring 45 into the limiting groove 47, thereby positioning the screw 44 and reducing the risk of the screw 44 falling and being lost.

[0025] Specifically, a sliding groove is opened on the surface of the fixing part 41, and three groups of rectangular holes are opened on the surface of the fixing part 41. The three groups of rectangular holes are connected to the sliding groove. The inner wall of the sliding groove on the surface of the fixing part 41 is slidably connected with a blocking ring 42. The surface of the blocking ring 42 is fixedly connected with three push blocks 43. The push blocks 43 are slidably connected to the inner wall of the rectangular hole.

[0026] In this embodiment, the push block 43 drives the shielding ring 42 to move, and the shielding ring 42 can shield the screw 44 to improve the appearance. At the same time, the shielding ring 42 fits against one end of the screw 44 to prevent the screw 44 from rotating.

[0027] Specifically, three grooves 46 are formed on the surface of the fixing member 41 , and the grooves 46 are for the screws 44 to enter. The three grooves 46 on the surface of the fixing member 41 can hide the screws 44 so that the screws 44 are flush with the surface of the fixing member 41 .

[0028] Specifically, an auxiliary device 5 is provided on the surface of the nut body 3, and the auxiliary device 5 includes a slider 51. Three groups of slide grooves 56 are opened on the surface of the nut body 3. The slider 51 is slidingly connected to the inner wall of the slide groove 56. The inner wall of the slider 51 is rotatably connected to a rotating rod 52, and the surface of the rotating rod 52 is fixedly connected to an auxiliary rod 53.

[0029] In this embodiment, when the auxiliary rod 53 is rotated, the auxiliary rod 53 and the nut body 3 are in a vertical state, and the nut body 3 can be tightened by the auxiliary rod 53, so that it is easy to manually disassemble without a wrench.

[0030] Specifically, a slot 54 is formed on the surface of the auxiliary rod 53 , and a limiting rod 55 is fixedly connected to the inner wall of the slide groove 56 on the surface of the nut body 3 , and the limiting rod 55 is engaged with the inner wall of the slot 54 .

[0031] In this embodiment, when the limiting rod 55 is inserted into the limiting groove 47 on the surface of the auxiliary rod 53, the auxiliary rod 53 can be kept in a horizontal state.

[0032] Working principle: When the equipment is connected to the interface, the nut body 3 on the tube body 1 is rotated, and the nut body 3 cooperates with the threaded end of the interface to achieve connection. By setting the stabilizing device 4, when the tube body 1 is connected through the nut body 3, the screw 44 is rotated, and the screw 44 can drive the auxiliary ring 45 to be inserted into the corresponding slot 48 on the surface of the connecting piece 2. After the insertion is completed, the screw 44 enters the groove 46 on the surface of the fixing piece 41 and is flush with the groove 46, pushing the push block 43, and the push block 43 drives the shielding ring 42 to shield the screw 44. At the same time, the screw 44 is against the inner wall of the shielding ring 42. By setting the stabilizing device 4, the stability effect of the bellows after connection can be improved, which can effectively reduce the existing bellows. When the connection is carried out, the main threaded connection method is adopted. When the nut is vibrated after connection, the nut is very likely to rotate, which leads to the loosening and instability of the bellows connection and leakage, thereby improving the stability effect of the bellows after connection.

[0033] By setting the auxiliary device 5, when it is necessary to manually rotate the nut body 3, the slider 51 and the auxiliary rod 53 are pushed upward to move the limiting rod 55 to the opening of the limiting groove 47 on the surface of the auxiliary rod 53, and then the auxiliary rod 53 is rotated to make the auxiliary rod 53 perpendicular to the nut body 3, so that the auxiliary rod 53 can apply force to the nut body 3, thereby controlling the rotation of the nut body 3. By setting the auxiliary device 5, it is convenient to assist the disassembly of the bellows, which can effectively reduce the problem that the existing bellows cannot be manually disassembled without a wrench due to the nut being too smooth and easy to slip when manually rotated by fingers, thereby being inconvenient to apply force, thereby improving the overall ease of use.
